Why Orchid Growers Use Fir Bark
Fir bark is one of the most common base materials in orchid potting mixes. It holds a moderate amount of moisture while still allowing air to reach the roots, and its rough surface gives roots something to grip as they grow.

Frequently Asked Questions
Can I use fir bark by itself, or does it need to be mixed with anything?
Fir bark can be used on its own as a base potting medium. Many growers also blend it with charcoal, sponge rock, or sphagnum moss depending on the orchid and growing conditions.
Which size should I order?
The 1-cubic-foot box is a practical choice for smaller collections and regular home repotting. The 2-cubic-foot box is better suited to larger collections, frequent repotting, orchid societies, and greenhouse use.
How often does fir bark need to be replaced?
Bark breaks down gradually over time. Most growers replace it at their normal repotting interval, or sooner if the mix looks compacted or is holding too much moisture.
Will every piece be exactly the same size?
No. This is a natural product so individual pieces may vary slightly in shape and size.
